My Media Center on Vista Premium will not stay as the top window. I have it
set up under the general settings to remain on top, but it always goes behind
the other windows when I am using it. This worked ok before though, but now
it is not working right.

What can I do to fix this since the box to keep the window on top is already
checked? For some reason it just is not working. I try to watch a show
while I work but the media center screen keeps falling behind the other
windows I am working on.
